Star moment: There is some strategy behind seating celebrities. They don't want to sit just anywhere. And that's why the Underground staff had its work cut out for it the night Lindsay Lohan, Bruno Mars, Nas and Cee Lo Green visited in August. ¿My partners and I ran in back to a seating chart to try to figure out who we should sit next to who and who would hate to be next to who,¿ said Dec, whose group also owns Underground. ¿It turned into a giant panic attack of confusion, like a high school cafeteria meets a wedding table placement meets an award show seating chart. ... We felt really uneasy about our choices as you could tell everyone's posses were checking out the other, evaluating who got the best seats and who got the worst." All was forgiven when Mars grabbed the mic and triggered a singalong.
